A new state budget plan includes money to rehabilitate a crowded Rhode Island homeless shelter, but spends far less than advocates had sought to address the state’s growing problem of homelessness. The budget proposal scheduled for a vote Tuesday in the state House of Representatives contains $1 million to renovate Harrington Hall, the state’s largest shelter for men. The Cranston facility often houses more than 100 men, but has only two working bathrooms. Homeless advocates had asked for $3.25 million for shelters and affordable housing subsidies.
